I'm always put off by asian authors who take legends, names, history, culture from different european countries, put it together and "create" their fantasy world.
I promise you, if I created a world mixing some bits of chinese, korean, thai and japanese culture without making a difference, people'd insult me ans say I'm racist and ignorant.
I wonder how the author will resolve this, because before the mom appeared, they seemed near the end of their relationship. ML was repeating his past relationship with his wife, but with the MC, even if they make up this time, nothing has changed.
